Radiometry and nuclear radiometric methods at MGRI is a direction related to the study of natural radioactivity and the tasks of nuclear geophysics. For practice, it means a set of methods providing prospecting and exploration, laboratory analysis of samples and development of gamma-ray well logging technologies.
The establishment and development of the Department of Radiometry (1930-1964), and then the Department of Nuclear Radiometric Methods (1964-1988) is inextricably linked to the development and implementation of methods for analyzing natural radioactivity and nuclear geophysics. methods of analyzing natural radioactivity and nuclear geophysics.
Brief overview
Contribution of V.I. Baranov
Under the leadership of Prof. V.I. Baranov in the 30-50s. Under the leadership of Prof. V.I. Baranov in the 30-50s of the twentieth century, the scientific bases of radiometric methods were created, New methods of natural radioactivity research were proposed: emanation survey, beta-analysis of powder samples, The foundations of modern gamma-ray well logging were laid.
